Hi. I went lookinmg for sunnies about a year ago. My Dad had pterygiums scraped off both eyes... not fun. Lots of salt water and sun exacerbates them. Water sunnies cut heaps of spray, as well as cut the harmful UV's.
Basically, UV-A and UV-B are bad, so look for lenses with 99% or 100% absorption. Polarised is good, as it cuts glare up from the water surface as well as lets you see INTO the water - you can see fish, rocks, shallow sandbar, etc.
So-called 'brown' lenses are better than 'grey' lenses on water as they cut more of the glarey blue segment of the light spectrum. Although grey lenses lets you see more natural colour.
You also want them to stay on in a wipeout. And not fog up.
Then there's style and branding.. whetever looks good.

Never come off despite some heavy faceplants. 100% UVA & UVB. Polarised. look fine. No pterygiums (so far). Costs about AU$85
